Tunnel Accept Mode
Settings
Description
Mode
Set the method used to start a tunnel in Accept mode. Choices are:
Disable
= do not accept an incoming connection.
Always
= accept an incoming connection (
default
).
Any Character
= start waiting for an incoming connection when any
character is read on the serial line.
Start Character
= start waiting for an incoming connection when the start
character for the selected tunnel is read on the serial line.
Modem Control Asserted
= start waiting for an incoming connection as long
as the Modem Control pin (DSR) is asserted on the serial line until a
connection is made.
Modem Emulation
= start waiting for an incoming connection when
triggered by modem emulation AT commands. Connect mode must also be
set to Modem Emulation.
Local Port
Set the port number for use as the network local port. The default local port
number for each supported serial line number progresses sequentially in
equal value so that Tunnel X: 1000X. For example:
Tunnel 1: 10001
Tunnel 2: 10002
Protocol
Select the protocol type for use with Accept Mode:
SSH
SSL
TCP (default protocol)
TCP AES
Telnet
TCP Keep Alive
Enter the time, in milliseconds, the SGX 5150 waits during a silent TCP
connection before checking if the currently connected network device is still on
the network. If the unit gets no response after 1 attempt, it drops the connection.
Enter 0 to disable. Blank the display field to restore the default.
TCP Keep Alive Interval
Enter the desired
TCP Keep Alive Interval
in milliseconds. This time interval is
the amount of time between probes to the remote host.
TCP Keep Alive Probes
Enter the desired
TCP Keep Alive Probes
in milliseconds. This time interval is
the amount of time the remote host is probed.
Initial Send
Enter the
Initial Send
data to be sent out the network upon connection
establishment before any data from the Line. It may contain one or more
Directives
of the form
%<char>
.
The Initial Send string can be entered in
Text
or
Binary
form. The Binary form
allows square braces
[ ]
to enclose one or more character designations
separated by commas. Use straight decimal numbers up to 255 or hexadecimal
numbers prefixed with
0x
up to
0xFF
within the square braces. To specify an
open brace in binary mode, use two in a row. Example (in Binary mode):
AB[255,0xFF]C[[D]
Results in a string containing binary values where
the dots appear:
AB··C[D]
Directives
%i
local IP address
%m
MAC address
%n
network interface name
%p
local port
%s
serial number
